An Optimal Design Method of Theoretical Line Loss Rate Benchmark Value for Medium Voltage Feeders and Its Application
摘要
Abstract
Currently,benchmark value setting of theoretical line loss rate for medium voltage (MV) feeders mainly depends on historical value,management experience or other factors,lacking theoretical basis.Thus,this paper proposes an optimal design method of benchmark value,based on fuzzy clustering and correction algorithm of ground state line.Firstly,from aspect of line loss contribution rate and data acquisition,a three-dimensional index system for feeders in MV distribution network is established.Secondly,fuzzy clustering with validity on the feeders is carried out and ground state feeder chosen.With help of equivalent resistance method and statistical method,theoretical line loss rate is calculated.Finally,optimal model of theoretical line loss rate benchmark value is established to obtain benchmark value.This model sets goal of making the largest feeder loss reduction space.Its constraints are operation management level,equipment frame condition and probability distribution of theoretical line loss rate of feeders.Analysis of an example,containing feeders from a city power supply enterprise in Guangdong Province,verified its scientific validity and universal applicability of the proposed method.关键词
